VI TRKFACE 



hand observations of a naturalist given in language 

 which may be understood by all, and the illustrations 

 by Thorburn, Douglas English and the author are 

 unsurpassed. If the quotations I have made from 

 this work tempt my readers, as I hope, to consult 

 Mr. Millais' volumes for themselves, I have not 

 written in vain. 



I have also made use of Mr. F. E. Beddard's 

 ' Mammalia,' in the Cambridge Natural History 

 Series, and have based such classification as was 

 necessary on that given by Mr. Beddard. I have 

 found much to help me in the British Museum 

 Guides and in Prof. Ridgeway's ^ Origin and In- 

 fluence of the Thoroughbred Horse.' 



My thanks are due to Dr. A. C. Haddon for so 

 kindly reading through the proof sheets and for 

 many helpful suggestions. I am also indebted to 

 those friends who have helped with the illustrations, 

 especially to Mr. H. C. Wood, and my kinsman, Mr, 

 H. R. Hall. 



Finally the book owes a deep debt of gratitude 

 to the sympathy and monumental patience of its 

 good publisher, Mr. R. Evan Adlard.
